Answer 1

1. C. Insulin human (rDNA) (Afrezza)
- Afrezza is the first of its kind as an inhaled rapid-acting insulin which peaks in the blood in 15minutes. This drug has been recommended for both type 1 and type 2 diabetics. However, further studies recommend this drug to be used in conjunction with long effect insulin injectables as the user is only limited to four inhalations. Aside from this, diabetics who had lung complications in the past are not advised to use this.

2. D. Diuretic
- The term diuretic means substances that induce urination. It is called as such because it promotes the process of diuresis or urine production.

3. D. Prevent or relieve coughing
- Antitussives are also known as cough suppressants. They work by inhibiting a part of the brain that coordinates the coughing reflex.

4. C. Iron
- Vitamin C is known to help absorb non-heme iron which is a form of iron that is harder for the body to absorb. Vitamin C reduces the non-heme iron so that it can be absorbed faster in the gastrointestinal tract.
